I could provide a double clickable app bundle for OS X. Would need some artwork 512x512px for the icon. Devs interested?

Here you go:

Very nice, however I should point out that the angel on there is the TT logo - which isn't associated with the MWTC release. You can find a non angel version on the MWTC game menu (and a screenshot of that can be found in the gallery too).

You could use the same image coroner used for the main menu (or the team logos and so on) and make certain elements (the rifle) break up the icon's silhouette like the wings of the plane do here:

The other thing you could do, if you'd like to keep the current design is spice it up by moving the texture to the background and placing the text in front, give it that shiny Apple UI look (not a simple gradient, look for tutorials on that), maybe play with it a bit further like in the following example:

Yes, that icon I made is just for the alpha-starter app (I didn't want to put too much work in it, since it was just for a user who requested an icon for a simple workaround-starter for the alpha) and I don't know how it will be used.

I made an Icon for TC Elite years ago, with the 'features' you mentioned (two TCE riflemen standing on a golden platform) and I would do another 'better' one if there's a demand for that.
